With one week left until voting day, a new survey released by Forum Research continues to show a three-way race in the Calgary-Centre by-election between Conservative Joan Crockatt, Liberal Harvey Locke, and Green Chris Turner.

As reported by the Globe & Mail, the survey of randomly selected Calgary-Centre voters released on November 17 showed Ms. Crockatt with 35% to 30% for Mr. Locke and 25% for Mr. Turner. New Democrat Dan Meades was in fourth place with 8%.

Another survey from Forum Research released last weekshowed Ms. Crockatt with 32% to 30% for Mr. Locke and 23% for Mr. Turner. New Democrat Dan Meades was in fourth place with 12%. Margins of error for these types of surveys typically range around five percentage points.

As I wrote last week, it appears that within a matter of months, the 40% margin of victory earned by former Conservative MP Lee Richardson in the 2011 federal election and 23% margin for the Conservatives found in a September survey of Calgary-Centre voters may have completely evaporated.

It is always important to approach surveys, like this interactive voice response (IVR) survey, with a healthy dose of skepticism. Survey results are a snapshot of the opinions of a surveyed group of individuals at a given moment in time. This said, surveys like this one can be an important indicator of trends.

The drop in Conservative Party support has led political watchers to wonder if this by-election could result in the election of the first non-Conservative Member of Parliament in Calgary since 1968. The potential for an upset has certainly bolstered the resolve of Ms. Crockatt’s two main opponents, Mr. Locke and Mr. Turner.

Ms. Crockatt earnedmixedreviews after participating in her first all-candidates forum at the East Village Neighbourhood Association on Saturday afternoon. This was expected to be the only time the Conservative candidate will publicly engage with her opponents at an organized forum.

On Saturday night, Mr. Turner’s campaign hosted what might have been the biggest actual political party of this by-election. More than 500 tickets were sold to the “Turning Point” event at Scarboro United Church. The event included a performance from Jay Ingram and the Scrutineers and speeches from Green Party leader Elizabeth May and environmentalist David Suzuki. Mr. Turner also received the endorsement of local author Fred Stenson, who ran as a Liberal candidate in the recent provincial election.

Steady in second place according to two recent polls, Mr. Locke is getting some pan-Canadian support from Liberal politicians. By my count, nine of the thirty-five Liberal Members of Parliament have visited the riding, including Bob Rae, Justin Trudeau, Ralph Goodale and Senators Terry Mercer and Grant Mitchell, and leadership candidate Martha Hall Findlay. Vancouver-Quadra MP Joyce Murray made her second visit to Calgary-Centre this weekend and Mr. Trudeau is expected to return to the riding this week before attending a rally in Edmonton. Liberal MLAs Kent Hehr, Darshan Kang, and Raj Sherman have also campaigned with Mr. Locke.

A fun fact and perhaps the closest comparison we have to this federal by-election in Calgary-Centre are by-elections that have taken place on the provincial level. In the four provincial by-elections held since 1992, opposition candidates were elected in three. In 1992, Calgary-Buffalo was held by Liberal Gary Dickson after the death of two-term Liberal MLA Sheldon Chumir. In 1995, the Progressive Conservative Shiraz Shariff narrowly held on to the Calgary-McCall constituency following the death of the former PC MLA.

The two most recent provincial by-elections saw opposition candidates elected in constituencies formerly held by the governing PCs. Liberal Craig Cheffins narrowly defeated the PC candidate to win a 2007 by-election in Calgary-Elbow, the constituency formerly represented by Premier Ralph Klein (Alison Redford would narrowly defeat Mr. Cheffins in the 2008 general election). In 2009, former Wildrose MLA Paul Hinman won a hotly contested three-way race in Calgary-Glenmore, defeating high-profile Tory Alderman Diane Colley-Urquhart and Liberal Avalon Roberts.

What does this mean for Calgary-Centre? At least when it comes to provincial by-elections, Calgarians have a track-record of sending the government a message.
